Is there an easier way to locate the vehicles Simeon wants?

Sometimes when Simeon sends a list of cars he wants, finding the more profitable ones can be tricky. But this latest list should have been the easiest cake-walk ever. FQ-2? Patriot? Fusilade? (Also Habanero and Gresley) Those are all the vehicles I get frustrated with when I'm trying to find anything good (be it fast or valuable).
However the game seems to have other ideas, as after 45 minutes of searching various areas, the Radius has overwhelmingly become Los Santos's most popular Hatchback/SUV. I literally counted 10 of them stopped in a single direction at a red light. Patriots have disappeared off the face of the earth, and the Sentinel XS seems to have replaced the Fusilade as the most popular 2-door coupe.
I just don't get it, the GTA Wikia says the following under it's entry on the FQ-2's location online:
The FQ 2 is a common vehicle, more so when it's being requested by Simeon Yetarian for his Import/Export Garage.
Normally I'd agree with the first part of that quote. They were common. Very common. Annoyingly common. But the second part of that quote seems to be an outright lie based on what I've seen for the better part of the last hour. The entry on the Fusilade makes claims to similar frequent spawning bolstered by being requested.
I'm not going to waste any more time on this particular request from Simeon, as my time would be more profitably spent driving a Sanchez around the racetrack solo at this point (~$850/minute -vs- the maximum payout of ~$6720 for an FQ2 or Patriot). But is there some trick to more easily locating vehicles on Simeon's list?

How do you find the cars Simeon wants?
This vehicle will be parked in one of 10 specific spawn spots:How often can you steal cars for Simeon?
If you follow through with it, however, it won't happen again that day because Simeon only asks for one car every 24 hour (real time) period. Any car you steal afterward will get the normal range of responses: one star wanted level, a bounty, or no reaction at all.How do you get Simeon to call you so you can buy properties?
The first solution is to simply walk to a store, which will be marked on your map by now. There are 20 on the map so it shouldn't be a long drive to the nearest one. Simply buy some snacks and walk out of the building, without robbing it. You should get the phone call as you leave the premises.How To Activate Simeon's Export Request l Unlock FREE Content l GTA Online
